BASIS OF PRESENTATION [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides the following steps to achieve the core principle (1) Identify the contract(s) with the customer, (2) Identify the performance obligations in the contract, (3) Determine the transaction price, (4) Allocate the transaction price to the performance obligations in the contract, and (5) Recognize revenue when (or as) the entity satisfies a performance obligation. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance, as amended, is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017, including interim periods within those reporting periods. Management’s assessment on revenue recognition by following the five steps resulted in no material changes from the current revenue recognition because the majority of revenues earned by the Company are not within the scope of ASU 2014-09. As interest income on loans and securities are both excluded from Topic 606, the majority of revenue earned is not subject to the new guidance. Service charges on deposit accounts, debit card interchange fees, and ATM fees are services provided that fall within the scope of Topic 606 and are presented within non-interest income as revenue when the obligation to the customer is satisfied. Gains on the sale of OREO fall within the scope of Topic 606 and are recognized as a credit to non-interest expense as an offset to writedowns of carrying value and losses on the sale of OREO, as permitted. The Company adopted Topic 606 as of January 1, 2018 with no material change in how revenues are recognized in the Company’s financial statements. Significant items of non-interest income are described below. Service charges on deposit accounts – Fees are earned from our deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees and overdraft fees are recognized at a point in time, since the customer generally has a right to cancel the depository arrangement at any time. The arrangement is considered a day-to-day contract with ongoing renewals and optional purchases, so the duration of the contract does not extend beyond the services already performed. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which we satisfy our performance obligation. Debit card interchange fees - Revenue earned from a portion of the fee charged to merchants for the immediate approval of credit for funds (whether debit or credit card usage) is recognized on a daily cash basis and the commission is paid through Premier’s third-party processor. The revenue is earned on a transaction basis determined by customer activity. Premier records this revenue on a gross revenue basis and expenses the processing charges incurred as a non-interest expense. Non-customer ATM fees – Fees charged to non-deposit customers for using bank owned automated teller machines is charged on a transaction basis and withdrawn from the users’ deposit account at another financial institution upon completion of the transaction. Gain on sale of OREO – A gain is recognized upon the sale of OREO when a contract exists between the seller and purchaser and the control of the asset is transferred to the buyer. The gain is then reported as a reduction of non-interest expense under the heading “Write-downs, expenses, sales of other real estate owned, net.” In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU makes several targeted improvement modifications to Subtopic 825-10, which (1) Require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, (2) Simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment and when an impairment exists, an entity is required to measure the investment at fair value, (3) Eliminate the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (4) Use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (5) Present separately in other comprehensive income the portion of the total changes in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option of financial instruments, (6) Require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial instruments, and (7) Clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The Company adopted subtopic 825-10 on January 1, 2018 which resulted in the use of an exit price rather than an entrance price to determine the fair value of loans not measured at fair value on a non-recurring basis. See footnote 7 for additional information on fair value. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This standard requires organizations to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing requirements for leases that were historically classified as operating leases under previous generally accepted accounting principles. This ASU will become effective for the Company for interim and annual periods beginning after December 15, 2018. The Company leases some of its branch locations. Upon adoption of this standard, an asset will be recorded to recognize the right of the Company to use the leased facilities and a liability will be recorded representing the obligation to make all future lease payments on those facilities. Management is currently evaluating the amounts to be recognized upon the adoption of this guidance in the Company’s financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments. This ASU replaces the measurement for credit losses from a probable incurred estimate with an expected future loss estimate, which is referred to as the “current expected credit loss” or “CECL”. The standard pertains to financial assets measured at amortized cost such as loans, debt securities classified as held-to-maturity, and certain other contracts, in which organizations will now use forward-looking information to enhance their credit loss estimates on these assets. The largest impact will be on the allowance for loan and lease losses. This ASU will become effective for the Company for interim and annual periods beginning after December 15, 2019, although early adoption is permitted beginning after December 15, 2018. The company has formed a committee to oversee the steps required in the adoption of the new current expected credit loss method. The committee has selected a third-party vendor to assist in data analysis and modeling as well as the required disclosures. Management is currently evaluating the impact of the adoption of this guidance on the Company’s financial statements. Upon adoption, an initial cumulative increase in the allowance for loan losses is currently anticipated by management along with a corresponding decrease in capital as permitted by the standard but cannot yet determine the one-time adjustment. In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU amends Topic 220, Income Statement – Reporting Comprehensive Income to permit the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and any future change in corporate income tax rates. The update does not affect the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations. The Company adopted ASU 2018-02 retroactively to December 31, 2017 as permitted by the guidance.
